TL594CDTBG

DC DC Switching Controllers Overview

The TL594CDTBG is a precision switchmode pulse width modulation control circuit manufactured by onsemi. It features an integrated oscillator with master or slave operation, two error amplifiers, and a 5.0 V reference with 1.5% accuracy. The device includes adjustable deadtime control and uncommitted output transistors rated for 500 mA source or sink current. It supports both push-pull and single-ended output configurations and incorporates undervoltage lockout protection.

DC DC Switching Controllers Feature Summary

• Integrated complete PWM control circuitry with on-chip oscillator
• Adjustable deadtime control for optimized switching performance
• Uncommitted output transistors capable of 500 mA source or sink current
• Supports flexible push-pull or single-ended output topologies

DC DC Switching Controllers Applications

• Switchmode power supply control systems
• DC-DC converter designs
• AC-DC power conversion applications

DC DC Switching Controllers Procurement Notes

Verify the package type matches the required SOIC-16 configuration. Confirm that the operating temperature range aligns with the specified industrial limits. Ensure compatibility with the intended voltage-mode control architecture. Check for lead-free compliance if required by specific environmental standards. Validate pinout compatibility during integration into existing PCB layouts.

DC DC Switching Controllers Selection Notes

Select this component when a fixed-frequency PWM controller is required for switchmode power supplies. Consider its 500 mA output drive capability for direct transistor driving in moderate power stages. Evaluate the need for master/slave oscillator synchronization if multiple converters are used. Assess whether the integrated 5.0 V reference meets system accuracy requirements without external components.

DC DC Switching Controllers Part Context

The TL594CDTBG belongs to the TL594 family of precision PWM control circuits. It is a widely used standard component in power electronics design. The 'C' suffix typically denotes the commercial temperature grade. The 'DTBG' suffix indicates the specific tape-and-reel packaging and lead-free status provided by onsemi.

DC DC Switching Controllers Replacement Considerations

The TL494 is a functionally equivalent part from the same manufacturer family. Cross-reference pinouts and electrical specifications before substitution. Verify that the replacement part meets the same thermal and voltage ratings.
